How to create soap envelope structure

Hello Friends,
I am working on a RFC to webservice sync scenario.Here I am getting response from webservice in soap envelope form which is not matching with my wsdl response structure. I have tried to create the envelope structure manually  but i dint get success. Can any body guide me how to over come with it.
(I have already checked 'Do not create soap envelop' in receiver soap addapter).
Regards,
jayesh.

Thanks Anupam and Jenny for your kind response.
I am wrking on PI 7.0. I dnt want soap envelope in payload so I have already checked the 'Do not create response' button still in response message I am getting the soap envelope.
I can use java or xslt but the the structure is not able to read the soap envelope. To read it I need to create same data structure which matches with the soap envelope.
this is the response I am getting through webservice.
<?xml version="1.0" encoding="UTF-8" ?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="urn:enterprise.soap.sforce.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<createResponse>
<result>
<errors>
<message>Config Master Record Type Name value is missing</message>
<statusCode>FIELD_CUSTOM_VALIDATION_EXCEPTION</statusCode>
</errors>
<id xsi:nil="true" />
<success>false</success>
</result>
</createResponse>
</soapenv:Body>
</soapenv:Envelope>
And this is the wsdl structure
<?xml version="1.0" encoding="UTF-8"?>
<ns0:createResponse xmlns:ns0="urn:enterprise.soap.sforce.com">
   <ns0:result>
      <ns0:errors>
         <ns0:fields/>
         <ns0:message/>
         <ns0:statusCode/>
      </ns0:errors>
      <ns0:id/>
      <ns0:success/>
   </ns0:result>
</ns0:createResponse>
Because of the soap envelope it is not able to read it. I have to create new structure.
Experts please help me to solve this problem.
Regards,
Jayesh.

    Thanks Sam,
    SOAP UI saved my life but that want last long.
    But still my issue is not resolved.
    I am using a plsql program to take the Values from SOAP envelop and pass it to web-service and get the responce.
    I am sure my approach is perfectly fine. because it is working fine with other examples, but mean while i have a WSDL link this is really big and my program is not working for this WSDL link.
    infact i am getting the output as the same XML of URL.
    Let me know if u can help me out.
    Thanks

  • How to create An Organisational Structure through Expertmode.

    Hi Experts..
    How can we create an org.structure through Expertmode!What are the different transactions we use to create various types of objects..
    Regards,
    Sai

    hai
    for creating org structure in export mode  u can navigate as Naaga has mentioned.
    or for creating the org unit the TCODE-->po10
    Job-->PO03
    Position-->PO13
    Work center--->PO01
    PFCT---> Task Catalogue
    PPO1--> general
    here when u want to create an object take the required transaction
    take object create  then the mainthing is it will ask for the realtionship
    if it isa root object u can cancel  other objects also u can cancel.
    the various relationships are defined in sap
    the standard AtoB  it reflects when the object relationship is defined from the bottom  like reports
    another one B--A  reflects top to bottom  like line supervisor of
    craete tehe object create the relationship  thsi is the process.
    but it is laborious. each one has to be attended individually.
    when u give one relationship the (A--B) the corresponding reverse relationship is
    B--A is automatically created

  • PB & web service : how to manipulate soap envelop ?

    rVal = Conn.CreateInstance(proxy_obj, "checkvatport", "")
    messagebox("test rval",string(rval))
    // Create proxy object
    try

      boolean w_t
      w_t = TRUE

       tns1__checkvatresponse str2
      str1.countrycode = "BE"
      str1.vatnumber = "0810416786"
      ls_a  = proxy_obj.checkvat(str1.countryCode,str1.vatNumber,str2.requestdate,str2.valid,str2.address)

    Now i tried the to cut and paste the above soap envelop in SOAPUI , and it gives me the exact same error message as in the soaplog.
    I then tried creating a request through SOAPUI but based on the wdsl ,SOAPUI is giving me a different soap envelop as the one PB generated ?
    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:ec.europa.eu:taxud:vies:services:checkVat:types">
       <soapenv:Header/>
       <soapenv:Body>
          <urn:checkVat>
             <urn:countryCode>?</urn:countryCode>
             <urn:vatNumber>?</urn:vatNumber>
          </urn:checkVat>
       </soapenv:Body>
    </soapenv:Envelope>
    If i enter parameters in the above envelop and check it through SOAPUI , i end up having the result i want.
    Is there any way we can manipulate the soap envelop contents ? Or does anyone have any idea why the soap envelop generated by PB ends up having the above mentioned error in the soaplog file ?
    What am i missing ?
    TIA
    John

    You're using the EasySOAP proxy.  You didn't mention what version of PowerBuilder, but if you're using a version that supports the .Net engine instead use that.  The EasySOAP web service support is quite old.
    Once you do that you won't be able to use the log.  Instead, use something like Fiddler to trap the request and response.

    I am new to SAP CRM 2007. I have a requirement in which I need to create a view which will retreive data from my custom z table. But when you create a view , the wizard ask for Model nodes and, Bol entity, Bol relation etc. Kindly let me know what data I need to enter here so that I can relate to my custom table. I think I need to create a bol structure for my ztable. Kindly guide me in this regard.
    Thanks & Regards,
      Sanjay

    I would recommend to rather use an encapsulation of the ztable into BOL than just trying to work with value nodes because it heavily simplifies building of the UI and code to load, edit and save.
    In order to achieve this you would either have to build a genIL component and assign it to the BOL component set addressed in the runtime repository of the UI component to make it available on the UI layer.
    If your table is very simple and does not require relations etc. you might save some work using the approach via "Simple Objects" concept of BOL which provides a pretty generic impelmentation that requires much less code and deep understanding of the BOL/ genIL.
    Pleasse refer to the respective IMG node under
    Customer Relationship Management -> CRM Cross-Application Components -> Generic Interaction Layer/ Business Object Layer -> Component-specific Settings
    Hope this helps.
